Setting up Muting Threshold Controls,
The Audio Restore is the upper limit for the audio C/N margin setting. Audio
will be muted when the C/N margin is below the Cutoff setting, and un-muted
(e.g., restored) when the C/N margin rises above the Restore setting for a preset
period of time. The adjustable operating range is from -2.0 to 20.0 dB. The
default setting for Audio Restore is 0.1.
Note: Muting Control must be set to Enable for these settings to be active.
